Item Void-aware routing protocols for underwater communication networks: A survey(2021) Nazareth P.; Chandavarkar B.R.Underwater Acoustic Sensor Networks (UASNs) is a technology used in several marine applications like environment prediction, defense applications, and discovering mineral resources. UASNs has several challenges like high bit error rate, high latency, low bandwidth, and void-node problem during routing. In the context of routing protocols for underwater communication networks, the void-node problem is one of the major challenging issues. The void-node problem arises in the underwater communication during the greedy-forwarding technique, due to which packet will not be forwarded further toward the sink. In this review paper, we analyze the void-node problem in underwater networks and issues related to the void-node. Also, we elaborate on the significant classification of void-handling routing protocols. We analyze both location-based and pressure-based void-handling routing protocols. © Springer Nature Singapore Pte Ltd 2021.Item Data formats and its research challenges in iot: A survey(2021) Mahanthappa S.; Chandavarkar B.R.In the current context, the increase in data generated by the heterogeneous IoT sensors results in several challenges to the IoT applications’ developers. One of the significant problems is handling nonstandardized zeta bytes of heterogeneous IoT data. Further, there is a lack of understanding of data generated by the sensors and incompatibility in representing the data. The objective of this survey paper is to introduce IoT sensors with their areas of applications, the different data formats, representing the data in an interchangeable format, and handling data as a stream. Further, this paper also presents challenges and research opening in IoT data. © Springer Nature Singapore Pte Ltd 2021.
